Abstract (en)
An information processing apparatus includes firmware incorporated in the apparatus; utility software that can be installed and uninstalled; a first restricting unit; and a second restricting unit. The information processing apparatus executes the firmware and the utility software to access a device. The firmware uses the first restricting unit to restrict use of the device on the basis of restriction information, supplies the restriction information to the utility software, and removes the restriction by the first restricting unit if an instruction to remove the restriction is received from the utility software. The utility software determines whether the use of the device has already been restricted by the second restricting unit when the utility software receives the restriction information from the firmware, and instructs the firmware to remove the restriction by the first restricting unit if the use of the device has already been restricted by the second restricting unit.
